True one-dimensional flow occurs when

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
the magnitude and direction of the velocity do not change from point to point in the fluid
the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
the direction and magnitude of the veiocity at all points are identical
